Speed Ramping

[Gil-galad]

Hello everyone.

I have a question about speed ramping. I'm directing a short film that we are shooting on the EX 1. We are planning to shoot the majority of it at 48 fps. I know that it's an easy, drop every other frame deal to get to 24 fps, but what other options are there? Can I go to 36 fps or even something like 41? I guess my question is when you are dropping frames in post, does the pattern need to be a set order, and if you deviate from that, you get frames jumping and lagging?

Does anyone has first hand experience with picking odd speeds from 48 or 60 fps?

Thanks so much,
Joe

AfterEffects has the ability to control the frame rate graphically (for the Pro bundle...) and so then you can just 'ramp' by creating a series of keyframes where the frame rate changes.

You can sort of 'manually' do this in FC (I use Express so maybe Pro has the graphical means...) where you change the frame rate, again based on keyframes. The speed option gives you frame rate in terms of percent, so just make a series of percent changes.

I was watching the special features for one of the bond movies, and there was a segment on how the filmmakers got a 'at speed looking' sequence, when in fact the vehicles were going about half speed. It wasn't just a simple undercranking at a set speed, but varied according to a 'dramatic' effect. That was 'in camera' rather than post production...
